Iyonix courts SCSI migrationBy Chris Williams. Published: 3rd May 2003, 17:01:12 | Permalink | Printable
Wanted: Third party developersCastle Technology have kicked started the pre-show news frenzy early this year by initiating the migration of existing SCSI interfaces to their XScale Iyonix platform. Like commuters ducking out of the office early to avoid the early evening traffic rush, Castle's Iyonix PR brigade have been feverishly churning out announcements this week prior to the Wakefield show - flood gates on high alert for the end-of-week-mad-news-dash and we all know R-Comp like to have the last word on csa.announce. Perhaps it's all merely a bid to dominate the headlines and make us out to be completely and utterly biased in favour of the hardware developer. And no pizza in sight either.
Having thrice read the emailed Castle bulletin (where every sentence is puncuated with 'SCSI') and consulting the terribly formal iconbar.com article on the issue, we realised exactly what Castle are up to and that is they've produced a SCSI filing system for Iyonix computers in order to ease the pain for third party developers when it comes to engineering drivers for the various SCSI interface cards available.
Existing SCSI podule cards can be fitted to Iyonixes via a backplane but they'll need their drivers updating, new 32 bit drivers when they're developed can be softloaded during Boot. Alternatively, again once suitable drivers have been written, SCSI PCI cards can be slotted into a free PCI slot in the Iyonix. PCI is a hell of a lot faster than the legacy Acorn podule system so here's looking forward to someone supporting an off the shelf SCSI PCI card.
"This addition of SCSI to RISC OS makes development of drivers for SCSI interfaces and other SCSI devices much easier", explains a Castle spokesman. "This ensures that IYONIX pc users can now benefit from being able to use high speed SCSI devices on their IYONIX pc systems."
To further court third party developers, Castle are releasing the necessary software interface (API) to their SCSI filing system via their website although it's not available just yet.
"Wait! I want to develop a SCSI driver too!" you cry. No fear, they'll also be releasing example driver code and the updated 32 bit drivers to the Acorn SCSI and Castle SCSI podule cards. So if a third party driver drought hits their SCSI subsystem as well as USB, you can always resort to using an existing podule card. Castle claim however that Iyonix compatible drivers for SCSI devices ranging from scanners to hard discs to CD-ROM drives have been produced or in the process of being produced.
